«Azofit» is the microbiological fertilizer that is used to increase crop yields. The product contains nitrogen fixing bacteria Azotobacter vinelandii, which are able to taken up nitrogen from air, also biologically active substance and microelements. One part of the biological nitrogen is used by the bacteria, another part evolves into soil in soluble form, easily accessible for crops. Thus, compensation of mineral nitrogen takes place. Azofit acts as biogenous elicitors, which form resistance to diseases and stress, increase the physiological resistance of plants to pathogens.
